The IR in IR blaster stands for infrared. Most remotes use infrared to communicate instructions to different devices. TVs, receivers, and media players like Blu-ray also use this. Some Android devices come with an IR blaster built into them. This allows you to control different devices with just a few short steps.But, Lenovo K6 Note does not come IR blaster therefore, You can't use your phone as universal remote as IR blaster is absent in this phone.

Lenovo K6 Note is equipped with Dolby Atmos.It allows film makers to place sound elements in a 3D space. With 5.1 and 7.1 systems, when you want to create the illusion that someone is behind the audience. therefore, the speakers are pretty loud and I really liked what I heard.
